On Wednesday, JPMorgan Chase's Jamie Dimon rejected a proposition requiring the bank to be burglarized pieces, saying the plan would 'damage the franchise business.'

Yet Wall Streeters say the concern is not visiting go away easily. As a matter of fact, they anticipate to listen to similar questions put to Bank of America & Citigroup when they report 4th-quarter earnings very early Thursday.

'If you're thinking about it for JPMorgan, you need to think about it for the various other banks that are having much more troubles,' said James Sinegal, banking expert with Morningstar.

'It specifies where the banks are simply also big,' said Erik Oja, US banking expert for S&P Capital IQ. 'I think they will certainly acquire questions about it,' he said of Bank of America and Citigroup.

Government authorities such as Sen. Elizabeth Warren, D-Mass., have long been requiring the large banks to shrink. However the idea acquired footing once more last week when it was floated by Goldman Sachs, a Wall Street insider.

The tension comes amidst expectations for a suppressed bank-earnings season and also raised volatility in the U.S. stock exchange along with continued legal concerns. Citigroup, for example, has actually already advised that $2.7 billion in legal prices will certainly moisten its 4th-quarter earnings.

JPMorgan, the largest US bank by properties, saw its shares tumble more than 5 percent Wednesday after the banking giant reported disappointing 4th quarter revenues. The stock closed down 3.45 percent to $56.81 a share.

The bank uploaded a revenue boost of 4 percent to $21.4 billion.

Wells Fargo's solid earnings could possibly intensify to the concept that the bigger banks would be better off in pieces, stated Oja. Wells is in the 'sweet spot' of under $2 trillion in possessions, making it the tiniest of the 4 huge banks, Oja said.
